Introduction to Design

Using the project plan that was developed in the Plan phase, your team should have enough information to develop a detailed design for each site and the entire network. The network design should contain, at a minimum:

•Routing and switching component connectivity

•WAN connectivity for intra- and inter-sites

•Software applications and configurations for routers and switches

•Power and environment

•Security

•Redundancy and failover

•Disaster recovery

For each site, in addition to the above, your design should include telephone circuitry, equipment racks with cabinet locations, and layouts. Each site should have a design that encompasses your network call processing, conferencing, and messaging requirements. The design should be scalable for future growth.
